Description

本発明は、紙折機、詳しくは用紙の滑り防止する用紙搬送駆動ローラに関するものである。   The present invention relates to a paper folding machine, and more particularly, to a paper conveyance driving roller that prevents paper from slipping.

本や封筒などに挿入する印刷紙を紙折機で折畳むこととはよく知られている。このような紙折機には、折畳む用紙を搬送駆動する駆動ローラとこの駆動ローラに用紙を押し当てる押圧ローラとにより、用紙の先端をバックル内に所定の位置まで搬入し、その用紙の搬送を更に続けることによりバックルの入口で用紙にたわみが形成される。そのたわんだ位置を先端にして、つぎの一対のローラ間に挿入して、その用紙を所定の位置で折畳むようにしたものがある。   It is well known to fold a printing paper to be inserted into a book or an envelope with a paper folding machine. In such a paper folding machine, the front end of the paper is carried into a buckle to a predetermined position by a driving roller for driving the paper to be folded and a pressing roller for pressing the paper against the driving roller, and the paper is conveyed. By continuing the above, a deflection is formed in the sheet at the entrance of the buckle. There is a type in which the sheet is folded at a predetermined position by inserting the bent position between the next pair of rollers.

ところで、このような紙折機は、駆動ローラは金属製とされ、用紙の搬送はその摩擦力で行われている。そのために折畳む用紙の紙質、たとえばアート紙、コート紙などの光沢紙あるいは印刷インクによっては滑りが発生し、この場合には用紙を折り畳むことができない。そのために紙折機によっては折畳む用紙の紙質を普通紙に限定したり、また、金属製の駆動ローラの表面にゴム帯を埋込み被着し、ゴムと金属とをローラの軸方向に交互に位置するようにして構成（サンドイッチローラ、コンビローラ）したりしている。
特開昭５７−２７８６６号公報 By the way, in such a paper folding machine, the drive roller is made of metal, and the paper is conveyed by the frictional force. For this reason, slipping occurs depending on the paper quality of the paper to be folded, for example, glossy paper such as art paper or coated paper, or printing ink. In this case, the paper cannot be folded. Therefore, depending on the paper folding machine, the quality of the paper to be folded is limited to plain paper, or a rubber band is embedded and attached to the surface of a metal drive roller, and rubber and metal are alternately placed in the axial direction of the roller. It is configured to be positioned (sandwich roller, combination roller).

しかし、ゴムと金属の２種類を纏めて精度良くローラを加工することは難しく、コストが高価となるばかりでなく、寿命も短く、さらにはリサイクル時の分別も面倒でリサイクル性も劣るという問題がある。   However, it is difficult to process a roller with two types of rubber and metal with high accuracy, which not only increases the cost, but also shortens the service life, and also makes it difficult to separate at the time of recycling, resulting in poor recyclability. is there.

本発明が解決しようとする課題は、紙折機に用いる用紙に搬送力を加える搬送駆動ローラを単一の金属製とするとともに、紙質にかかわらず正確に折畳むことができ、斯かる問題を解消する点である。   The problem to be solved by the present invention is that the conveyance drive roller for applying conveyance force to the paper used in the paper folding machine is made of a single metal and can be folded accurately regardless of the paper quality. It is a point to cancel.

本発明は、用紙に搬送力を加える搬送駆動ローラと、前記ローラにより搬送される用紙の先端を所定の位置まで挿入するバックルと、前記バックルから食み出し、用紙に加えられる搬送力でたわめられた端部を挟んで強圧する一対の折畳みローラとを備えてなる紙折機において、前記搬送駆動ローラを金属製とするとともに、前記搬送駆動ローラの外周表面に圧接する用紙に食い込む突起を一様に形成してなることを最も主要な特徴とする。   The present invention includes a transport driving roller that applies a transport force to the paper, a buckle that inserts the leading end of the paper transported by the roller to a predetermined position, and a transport force that protrudes from the buckle and is applied to the paper. In the paper folding machine comprising a pair of folding rollers that press strongly with respect to the end portions formed, the transport driving roller is made of metal, and a protrusion that bites into the paper that presses against the outer peripheral surface of the transport driving roller The most important feature is that it is uniformly formed.

本発明によれば、折用紙に搬送力を加える用紙搬送駆動ローラを金属製とするとともに、その外周表面に、搬送する用紙に食い込む突起を一様に形成しているので、搬送する用紙はその紙質にかかわらず突起に食い込まれて確実に搬送される。これにより折畳む用紙の紙質にかかわらず正確に折畳め、かつ、突起は用紙に食い込む程度であり折畳み後の用紙の印刷面にこの突起の痕跡も目立たず良質の折畳み用紙を得ることができる。また、紙折機に用いる搬送駆動ローラを金属製とするので、印刷インク、溶剤などに強く耐久性を有し、さらには金属の単一材質であることから、リサイクル時の分別の面倒も解消することができる。   According to the present invention, the paper transport driving roller that applies the transport force to the folded paper is made of metal, and the protrusions that bite into the paper to be transported are uniformly formed on the outer peripheral surface thereof. Regardless of the paper quality, it is bitten by the protrusions and reliably conveyed. This makes it possible to fold the paper accurately regardless of the quality of the paper to be folded, and the protrusions bite into the paper, and the printed surface of the paper after folding has no noticeable traces of the protrusions. . In addition, since the transport drive roller used in the paper folding machine is made of metal, it is highly durable against printing inks and solvents, and since it is a single metal material, it eliminates the hassle of sorting during recycling. can do.

紙折機に用いる用紙搬送駆動ローラを単一の金属製とするとともに、紙質にかかわらず正確に折畳むことができるようにする目的を、折用紙に搬送力を加える金属製の用紙搬送駆動ローラの外周表面に、搬送する用紙に食い込む微小突起を一様に形成することにより達成した。   The paper transport drive roller used in the paper folding machine is made of a single metal, and the metal paper transport drive roller that applies a transport force to the folded paper for the purpose of accurately folding it regardless of the paper quality This is achieved by uniformly forming fine protrusions that bite into the sheet to be conveyed on the outer peripheral surface of the sheet.

図１は実施例に係る紙折機の構成を示す構成図で（ａ）は側面図、（ｂ）は用紙押圧部の拡大断面図である。紙折機１は、用紙を搬送駆動する鉄などの金属製の駆動ローラ２とこの駆動ローラ２に用紙Ｐを押し当てるゴム製の押圧ローラ３および４と用紙挿入用のポケットを備えるバックル５とにより構成されている。バックル５は用紙を挿入する深さを設定する位置調整可能のストッパ５ａを有し、押圧ローラ３と４との間に配置されている。なお、ローラ２をゴム製の押圧ローラとし、ローラ３または４のいずれか一方、または両方を金属製の駆動ローラとしても良い。   FIG. 1 is a configuration diagram illustrating a configuration of a paper folding machine according to an embodiment, in which (a) is a side view and (b) is an enlarged cross-sectional view of a paper pressing portion. The paper folding machine 1 includes a driving roller 2 made of metal such as iron for conveying and driving paper, rubber pressing rollers 3 and 4 for pressing the paper P against the driving roller 2, and a buckle 5 having a paper insertion pocket. It is comprised by. The buckle 5 has a position-adjustable stopper 5 a that sets the depth of paper insertion, and is disposed between the pressing rollers 3 and 4. The roller 2 may be a rubber pressure roller, and either one or both of the rollers 3 and 4 may be a metal drive roller.

紙折機１に図示しない搬入ローラで搬入された用紙Ｐは駆動ローラ２と押圧ローラ３との間で受け取りバックル５内へ送られる。バックル５内へ挿入された用紙Ｐの先端はストッパ５ａに当接して停止するが、駆動ローラ２の駆動で用紙Ｐは送り続けられるので、用紙Ｐはバックル５の入口からはみ出す部分でたわむ。そして、そのたわみ端を先頭にして駆動ローラ２と押圧ローラ４との間に挿入され、駆動ローラ２と押圧ローラ４でたわみを強圧して用紙Ｐを所定の位置（ストッパ５ａの位置により決められた位置）で折り畳んで搬出される。   The paper P carried into the paper folding machine 1 by a carry-in roller (not shown) is received between the driving roller 2 and the pressing roller 3 and sent into the buckle 5. The leading edge of the paper P inserted into the buckle 5 stops by abutting against the stopper 5a. However, since the paper P is continuously fed by the driving roller 2, the paper P bends at a portion protruding from the entrance of the buckle 5. Then, it is inserted between the driving roller 2 and the pressing roller 4 with the bending end as the head, and the deflection is strongly applied by the driving roller 2 and the pressing roller 4 so that the paper P is determined by a predetermined position (the position of the stopper 5a). Folded and unloaded at the same position.

ところで、特にたわみ端を先頭にして駆動ローラ２と押圧ローラ４との間に挿入するとき、用紙Ｐの搬送を停止する力が加えられる。その停止力に抗するためにこの実施例では、駆動ローラ２の表面に図１（ｂ）に示すように微小の突起２ａが形成されている。この突起２ａは、駆動ローラ２の軸方向（長さ方向）に適宜の長さで複数区分し、その１区分おきごとの領域の周面に多数一様に形成されている。したがって、この突起２ａの形成に要する彫り起しなどの手間を少なくするとともに、いかなるサイズの用紙の折畳みにも適応することができる。   By the way, particularly when the sheet is inserted between the driving roller 2 and the pressing roller 4 with the deflection end at the head, a force for stopping the conveyance of the paper P is applied. In this embodiment, a minute protrusion 2a is formed on the surface of the driving roller 2 as shown in FIG. The protrusions 2a are divided into a plurality of sections with an appropriate length in the axial direction (length direction) of the drive roller 2, and a large number of protrusions 2a are uniformly formed on the peripheral surface of every other section. Therefore, it is possible to reduce the trouble of engraving and the like required for forming the protrusions 2a, and to adapt to folding sheets of any size.

突起２ａの高さ、すなわち駆動ローラ２と押圧ローラ３で用紙Ｐを押圧した場合に用紙Ｐに食い込む深さは、用紙Ｐの厚みＤの１／２程度とされ、普通紙の厚みの１／２である０．０４ｍｍ程度としている。０．０４ｍｍ程度以下であれば普通紙の厚みで如何なる紙質であっても折畳み後の用紙の印刷面にこの突起の痕跡も目立たず、かつ用紙Ｐの搬送を確実に行うことができる。なお、普通紙よりも厚い用紙であっても０．０４ｍｍ程度の食い込み深さで十分に搬送を行うことができるが、普通紙よりも薄い用紙では、突起の痕跡を目立せないために０．０４ｍｍ以下とする必要がある。   The height of the protrusion 2a, that is, the depth of biting into the paper P when the paper P is pressed by the driving roller 2 and the pressing roller 3, is about ½ of the thickness D of the paper P, and is 1 / th of the thickness of the plain paper. 2, which is about 0.04 mm. If the thickness is about 0.04 mm or less, the traces of the protrusions are not noticeable on the printed surface of the folded paper regardless of the quality of the plain paper, and the paper P can be reliably conveyed. Even if the paper is thicker than plain paper, it can be sufficiently transported with a bite depth of about 0.04 mm. However, if the paper is thinner than plain paper, the trace of the protrusion cannot be noticed. 0.04 mm or less is necessary.

図２は他の実施例に係る紙折機の構成を示す構成図、図３は図２に示す他の実施例に係る紙折機における搬入ローラ部の斜視図である。紙折機１１は、ローラ１２と、このローラ１２の円周方向に沿って配置された複数の押圧ローラ１３、１４、１７と、用紙挿入用のポケットを備える第１のバックル１５と、用紙挿入用のポケットを備える第２のバックル１８と、切換ゲート１６と、金属製の給紙（搬入）ローラ１９と、給紙台２１により構成されている。   FIG. 2 is a configuration diagram showing a configuration of a paper folding machine according to another embodiment, and FIG. 3 is a perspective view of a carry-in roller portion in the paper folding machine according to another embodiment shown in FIG. The paper folding machine 11 includes a roller 12, a plurality of pressing rollers 13, 14, and 17 disposed along the circumferential direction of the roller 12, a first buckle 15 having a paper insertion pocket, and paper insertion A second buckle 18 having a pocket for use, a switching gate 16, a metal paper feed (loading) roller 19, and a paper feed table 21 are included.

第１のバックル１５および第２のバックル１８はそれぞれに用紙を挿入する深さを設定する位置調整可能のストッパ１５ａと１８ａを有し、第１のバックル１５は押圧ローラ１３と１４との間に配置され、第２のバックル１８は押圧ローラ１４と１７との間に配置されている。そして、切換ゲート１６は第２のバックル１８の入口に配置されている。   The first buckle 15 and the second buckle 18 have position-adjustable stoppers 15a and 18a for setting the depth for inserting the paper, and the first buckle 15 is interposed between the pressing rollers 13 and 14. The second buckle 18 is disposed between the pressure rollers 14 and 17. The switching gate 16 is disposed at the entrance of the second buckle 18.

この紙折機１１で用紙Ｐを折畳む場合、用紙Ｐを１箇所で折畳むとき切換ゲート１６を、図２に実線で示すように第２のバックル１８の入口を閉鎖する。この場合は、給紙台２１上の用紙Ｐたとえば１枚が搬入ローラ１９によりローラ１２と押圧ローラ１３との間に送られ、その用紙Ｐの先端は第１のバックル１５内へ挿入される。バックル１５内へ挿入された用紙Ｐの先端はストッパ１５ａに当接して停止するが、搬入ローラ１９の駆動で用紙Ｐは送り続けられるので、用紙Ｐはバックル５の入口からはみ出す部分でたわむ。   When the paper P is folded by the paper folding machine 11, the switching gate 16 is closed when the paper P is folded at one place, and the entrance of the second buckle 18 is closed as shown by a solid line in FIG. In this case, for example, one sheet P on the sheet feeding table 21 is sent between the roller 12 and the pressing roller 13 by the carry-in roller 19, and the leading end of the sheet P is inserted into the first buckle 15. The leading edge of the paper P inserted into the buckle 15 stops by abutting against the stopper 15 a, but the paper P continues to be fed by the driving of the carry-in roller 19, so that the paper P bends at a portion protruding from the entrance of the buckle 5.

そして、そのたわみ端を先頭にしてローラ１２と押圧ローラ１４との間に挿入され、ローラ１２と押圧ローラ１４でたわみを強圧して用紙Ｐを所定の位置（ストッパ１５ａの位置により決められた位置）で折り畳んでローラ１２と押圧ローラ１７の間に送られて搬出される。   Then, the deflection end is inserted between the roller 12 and the pressure roller 14 with the deflection end as the head, the deflection is strongly applied by the roller 12 and the pressure roller 14, and the sheet P is positioned at a predetermined position (a position determined by the position of the stopper 15a). ) And is sent between the roller 12 and the pressure roller 17 and carried out.

また、用紙Ｐを２箇所で折畳むとき切換ゲート１６を、図２に点線で示すように第２のバックル１８の入口を開放する。この開放によりローラ１２と押圧ローラ１４でたわみを強圧して用紙Ｐを所定の位置で折り畳んだその先端を第２のバックル１８内へ挿入される。バックル１８内へ挿入された用紙Ｐの折り畳んだ先端はストッパ１８ａに当接して停止するが、搬入ローラ１９の駆動で用紙Ｐは送り続けられるので、用紙Ｐは第２のバックル１８の入口からはみ出す部分でたわむ。   Further, when the paper P is folded at two places, the switching gate 16 is opened, and the entrance of the second buckle 18 is opened as shown by a dotted line in FIG. With this opening, the deflection is strongly applied by the roller 12 and the pressing roller 14, and the leading end of the sheet P folded at a predetermined position is inserted into the second buckle 18. The folded leading end of the paper P inserted into the buckle 18 comes into contact with the stopper 18a and stops. However, since the paper P is continuously fed by the driving of the carry-in roller 19, the paper P protrudes from the entrance of the second buckle 18. Deflection in part.

そして、そのたわみ端を先頭にしてローラ１２と押圧ローラ１７との間に挿入され、ローラ１２と押圧ローラ１７でたわみを強圧して用紙Ｐを所定の位置（ストッパ１８ａの位置により決められた位置）で折り畳んで搬出される。すなわち、切換ゲート１６の切換で用紙Ｐを所定の１箇所と２箇所を選択して折畳むことができる。   Then, the deflection end is inserted between the roller 12 and the pressure roller 17 with the deflection end as the head, the deflection is strongly applied by the roller 12 and the pressure roller 17, and the sheet P is positioned at a predetermined position (position determined by the position of the stopper 18a). ) Is folded and carried out. That is, the sheet P can be folded by selecting one predetermined place and two places by switching the switching gate 16.

この実施例では、ローラ１２と搬入ローラ１９を鉄などの金属製とし、押圧ローラ１３、１４、１７をゴム製とされ、主として搬入ローラ１９を用紙Ｐに搬送力を加える搬送駆動ローラとしている。そして搬入ローラ１９の表面に、図１（ｂ）で示す微小の突起２ａと同様の突起が図３に示すように、搬入ローラ１９の軸方向（長さ方向）に適宜の長さで複数区分した、その１区分おきごとの領域１９ａの周面に多数一様に形成されている。   In this embodiment, the roller 12 and the carry-in roller 19 are made of metal such as iron, the pressure rollers 13, 14, and 17 are made of rubber, and the carry-in roller 19 is mainly a carry drive roller that applies a carry force to the paper P. Then, on the surface of the carry-in roller 19, a projection similar to the minute projection 2a shown in FIG. 1B is divided into a plurality of sections with appropriate lengths in the axial direction (length direction) of the carry-in roller 19 as shown in FIG. In addition, a large number are uniformly formed on the peripheral surface of the region 19a every other section.

このように搬入ローラ１９に突起を形成しても、用紙Ｐの折畳み先端が駆動ローラ１２と押圧ローラ１７との間に挿入されるまで、搬入ローラ１９によりその用紙Ｐに搬送力が加えられる場合には有効である。逆に金属製のローラ１２を搬送駆動ローラとしその表面に図１（ｂ）で示す微小の突起２ａを形成すれば、搬入ローラ１９の表面に形成する突起を省略することも可能である。この場合、ローラ１２をゴム製の押圧ローラとし、ローラ１３、１４、１７のいずれかを金属製の駆動ローラとし、その駆動ローラの表面に図１（ｂ）で示す微小の突起２ａを形成するようにしても良い。   Even if the protrusion is formed on the carry-in roller 19 in this way, the carrying force is applied to the paper P by the carry-in roller 19 until the folding tip of the paper P is inserted between the driving roller 12 and the pressing roller 17. Is effective. On the contrary, if the metal roller 12 is used as the transport driving roller and the minute projection 2a shown in FIG. 1B is formed on the surface thereof, the projection formed on the surface of the carry-in roller 19 can be omitted. In this case, the roller 12 is a rubber pressure roller, and any one of the rollers 13, 14 and 17 is a metal driving roller, and the minute protrusion 2a shown in FIG. 1B is formed on the surface of the driving roller. You may do it.
